Pat Price is a Remote Viewer who claims ETs have four bases around the world and that he's RVed them. Their locations are as follows.
'A famous set of caves in the Pyrenees have ancient drawings of ancient astronauts and flying spacecraft,' Atwater explained. 'And there have been a number of sightings here.'
Mt. Perdido, aka Mt. Perdu, is 3,352 m, 11,007 ft. high and is the third highest mountain in the Pyrenees. It's about a quarter inch west of Andorra. Price reported that the main base was protected around a 2-mile perimeter with detectors. Several craft were in the launch recovery area and had what looked like an electromagnetic field propulsion system.
The highest mountain (2,592 m, 8,503 ft) in Zimbabwe, formerly Rhodesia, Africa.
'Actually, it's more of a maintenance and tech center,' Price viewed. 'This base looks like overhaul and maintenance unit. I see lots of spare equipment. Parts are being welded in a vacuum area with window area then parts are fused. A grayish white powder is pasted on both parts then fused.'
His attention was drawn to unit that several were working on. It is a tubular grid system 'for ionizing a layer of air.'
Mount Hayes (Alaska):
It appears to be a weather and geological center and has similar security measures to prevent discovery. He described 'computer equipment' and followed leads on an 'oscilloscope' which led to a small box like structure which contained rotational antenna that sat on top of a mountain peak.
The receiver seemed to be part of a detection system.
'If they were discovered,' Price wrote, 'personnel are deployed physically in activity to make sure of failure of that certain project. This site has also been responsible for strange activity and malfunction of US and Soviet space projects.'
Atwater suggested that if a probe was launched over this part of Alaska, that it might be interfered in some way, to prevent detection of the Mt. Hayes base.
'It comes to mind that these 'people' have infiltrated all government in sensitive positions, not to control government, the processes or people, but rather to be in positions of power to stop politically any activity that may produce a result that could cause discovery.'
a personnel center, in Australia's Northern Territory.
'It is interesting that this unit appears to have the most personnel. There are personnel from the other three sites here, like a rest and recreation area.'
For a few moments, Price felt slightly disoriented and decided they had detected him so he led them to Melbourne.
Price returned to the site and saw vehicles from the other bases, with each having different ID marks that correspond to each site's different functions.
'Mt. Ziel had personnel for all bases and is the homosapiens introduction point.' he observed.
Price also noted that the site should be approached with caution and that the area was under alert at that moment.
I don't know for certain if any of this is true but with all of the UFO and USO sighting around the world there would have to be a base somewhere. At least for convience if nothing else. Otherwise they're making trips from their homeworld or base away from Earth and back everytime. Which I see as much less likely.
